Not a bad effort, but not what I'm looking for when I'm ready to settle into a movie either. The premise was old, guy's daughter dies due to industrial pollution & he wants to stop the polluting. Fair enough. But then we get into character development. Yawn. So at this point, I'm only still in it for the lurking henchmen, who could have been scarier. In fact, it's never scary at all, except for maybe one jump when the (epic) devil appears in the hallucination at the end. Had the entire film been like that I would have liked it. But it was a hum drum drama with lame characters instead. I will give props though for a good evil corporate bad guy, a likable everyday hero, & surprisingly great visuals in the final hallucination.
So in summary, it really lacked punch of any kind, dragged & just took too long to reach the great but brief denoument with a cute Fallen twist in the final shot.
